With the environment and sustainability firmly in mind the Dell Froot concept saves the planet courtesy two projectors: One for the virtual keyboard, and another for the monitor.

Designed by Pauline Carlos as part of a sustainability contest sponsored by Dell, the Froot also uses a colorful case that's constructed out of a biodegradable starch-based polymer. As it's a futuristic concept, the lack of a mouse is understabdable—we'll no doubt be using our brains by then.

More seriously, Pico projectors are *almost* there, but not quite, otherwise I'd be asking why this is still just a concept. [Behance Network via technabob via OhGizmo]
